Determining load weights

Ebook "Hoisting and rigging: Safety manual" is intended as a working guide for training workers and supervisors in the fundamentals of safe rigging and hoisting. The information covers not only ropes and knots but hoisting equipment from cranes to chainfalls and rigging hardware from rope clips to spreader beams. Equally important is the attention paid at every point to correct procedures for inspection, maintenance, and operation.

Respiration rate, sensory attributes, change in color, physiological loss in weight, chlorophyll and beta - carotene content and microbial loads were determined during storage of mint leaves at 10 and 27ᵒC to find an optimal gas composition to extend the shelf life. The Low Density Poly Ethylene (LDPE) bags with a thickness of 152 µ which recorded the lowest permeability to oxygen (1067 ml/m2 /day) was selected and used for packaging mint leaves.

This paper presents the effect of carrageenan (CG) on some characteristics and drug release of allopurinol in the presence of polyethylene oxide (PEO) as a dispersion aid agent. The samples were prepared in film shape by solution method, in which, the content of PEO was changed from 1 wt.% to 5 wt.% and the content of allopurinol was fixed at 10 wt.% in comparison with carrageenan weight. Fourier transforms infrared (FTIR) spectroscopy and Field emission scanning electron microscopy (FESEM) methods were used to evaluate interactions and morphology of CG/PEO/allopurinol films.

The use of industrial waste water for irrigation through drip system has emerged a very important way to utilize its nutrients and removal of its pollutants load by cultivating various crops (tomato, brinjal). An experiment was conducted to evaluate the impact of textile factory effluents (0, 10, 35, 75 and 100% concentration) on germination and some physiological parameters like biomass production, root development in vegetable crop. Plants were raised in small pots in triplicate and irrigated with various concentrations (0, 10, 35, 75 and 100%) of effluent.

Prevailing high temperature during harvesting to consumption of grapes in India results in accelerated water loss, faster respiration, physiological weight loss, rachis browning, berry shattering, poor shelf life and finally leads to significant post-harvest losses. Fruit surface is protected by the application of coating to maintain its freshness and shelf life for longer duration.

Recycling and reuse of solid wastes as alternative building materials present interesting possibilities for economy on waste disposal sites and conservation of natural resources. This paper investigates the physical and mechanical properties of solid cement bricks manufactured with crushed clay bricks as recycled aggregates. Four series of mixtures with cement content 100, 150, 200 and 300 kg/m3 were prepared. In each series, either natural fine aggregate, coarse aggregate or both were replaced with crushed brick aggregates (CBA) at 0%, 50% and 100% by volume.

Fresh to weathered metarhyolites crop out in the Ilgın (Konya) area of the Afyon-Bolkardağ Zone. Determination of the development of weathering was studied by physical (i.e. specific gravity, dry unit weight, saturated unit weight, porosity, void ratio, and degree of saturation by weight) and mechanical (i.e. point load) properties and the “point rock change value” (RCVp ) and “point rock change ratio” (RCRp ) values of the metarhyolite rock samples.

Impact resistance and strength performance of concrete mixtures with 0.36 and 0.46 water–cement ratios made with polypropylene and silica fume are examined. Polypropylene fiber with 12-mm length and four volume fractions of 0%, 0.2%, 0.3% and 0.5% are used. In pre-determined mixtures, silica fume is used as cement replacement material at 8% weight of cement. The results show that incorporating polypropylene fibers improves mechanical properties.

The paper deals with observing the behaviour of concrete composites with addition of fibres under ambient and elevated temperature with the aim to determine the mechanical properties of materials. The experimental tests were conducted on three selected concrete composites which differ in a type and content of fibrous reinforcement used. The experimental work carried out was divided into several phases. First of all it was necessary to leave the produced specimens aging and drying in order to minimize the risk of unexpected damage caused by concrete spalling during heating.

The collective load is the basis for determining the average speeds (2,387 min–1) and the average driving speed (111 km/h). For each of the load cases the tooth load acting on the pinion and the reaction loads from the bearings have to be calculated both for forward and backward motion (percentage times 50 % each). In addition to these forces, the bearings are subjected to loads due to the rotor weight, the unbalanced magnetic pull, unbalanced loads and rail shocks. Of these loads only the rotor weight, GL, is known; therefore, it is multiplied by a supplementary factor fz = 1.5..
